The new leased site will support the continued expansion of the Tully’s Coffee brand and wholesale business, the national expansion of other Green Mountain brands and the growth of the company’s single-cup business, according to Green Mountain.

The Sumner facility is expected to be operational this fall.

“We are extremely excited about joining the Sumner community and are grateful for the support we received from the state of Washington Department of Commerce, the Economic Development Board for Tacoma-Pierce County and the city of Sumner,” said Jon Wettstein, vice president of supply chain operations for Green Mountain’s Specialty Coffee Business Unit. “Our investment in a new, modern site in Sumner will complement our existing facilities in our home state of Vermont and in Knox County, Tenn. It will allow us to accommodate the significant growth and expansion we are planning for the Tully’s business, as well as for the expansion of our other brands on the West Coast.”

The Sumner site is the latest in a series of expansions for the company’s Specialty Coffee Business Unit. In 2007, new K-Cup production lines were added to its Waterbury, Vt., plant, and the company opened a second manufacturing site in Essex, Vt. In September 2008, the company opened a facility in Knox County, Tenn., and is in the process of expanding operations there.

Green Mountain’s Specialty Coffee business unit produces coffee, tea and hot cocoa from its family of brands, including Tully’s Coffee, Green Mountain Coffee and Newman’s Own Organics coffee.
